Firstly, I'm a huge fan of proper home working. Simply, it works for me.
The general "vibe" I get from this is that that new management has arrived and is concerned about productivity. I assume that if new management has arrived, they would or should know what productivity levels should be and that yahoo remote staff are lacking. If so, then from a management POV, it does seem quickest and simplest to notionally get everyone back to base and kind of hit a reset switch.
If yahoo is now a low ranked place to work, then I can well imagine that in general its employees are a bit low ranked too, and perhaps some of the more lazy ones looking for a lax easy life. Presumably the quality people will have left. In which case, remote working cant work well at all.
Don't get me wrong, I'm not blaming the employees, this can only happen or go wrong if management lets it. But, I think one should support a new regime that is presumably trying to sort it out. Presumably, and if it were me, they will assess the situation and bit by bit allow people out of the office again, but with new procedures, guidelines or what ever.
So, to be honest, I think I can see what yahoo is doing. Yes it is painful for the good remote employees that are left there, but if thing are going wrong, they need to support the attempts to fix it.
Or...... I've missed the point somewhere.
